Information on automatic trunk lid controls
(electrohydraulic)
Caution!
When working on the open hydraulic system, ensure extreme
cleanliness, as otherwise even the smallest dirt particles in the
hydraulic system can lead to malfunctions.
Function description (open/close):
Operation of the trunk lid is only possible via;
-
Control button in passenger compartment (opening only)
-
Control button outside on trunk lid (opening and closing when
car is not locked)
-
Remote control switch on key (opening only)
-
Control button in handle on tailgate trim (closing and opening)
Note:
If a control button is operating again during an opening or
closing procedure, this procedure is stopped. If a control
button is operated again, this changes the direction in which
the trunk lid moves (except for passenger compartment and
remote control buttons, opening only here).
Description of operation (antirepeat device):
An antirepeat device is fitted to prevent the hydraulic control unit
from overheating.
The total motor running time of the hydraulic control unit is
recorded by a counter. If the motor is not activated, this counter is
reduced by a third of the pause time. If the counter exceeds a total
running time of 2 minutes, no further actuations are accepted.
Thus, for a motor running time exceeding 2 minutes, an enforced
pause which is three times as long is engaged.
After a cooling-down period of 6 minutes, it is again possible for
the motor to run for 2 minutes.
Note:
However, an actuation which is in operation is not terminated
even if the maximum running time is exceeded.
